possible invincibilty?

havent been able to actually build this deck and thus havent been able to playtest it... the theory as follows is simple..
survive via holy day until cho manno or stuffy doll has pariah.. (for more fun add spirit loop to Stuffy doll) use idyllic tutor to pull your hondens and Auramancies.. you will need 2 to ensure that they are not removed. also make sure u have a spirit loop on at least one true believer for that will protect from burn and other such while auramancy is in effect. bring elspeth out once you have the defensive force to protect her, then let her ultimate go after using her soldier building abilities. follow with planar cleansing to end the game.
